The E2E testing layer for AI-driven development

What is your company going to make? Please describe your product and what it does or will do.

We build Lark to let teams write end-to-end tests in plain English. Our product validates dashboards, APIs, SDKs, and full product flows without the fragile test code developers normally maintain. It runs continuously on feature branches, in CI, or even in production, so teams catch issues early and test coverage stays solid despite changes.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and the company will stay based here after YC.

Explain your decision regarding location.

San Francisco is where we built the product and where we can connect directly with early customers in developer and product teams. Being here puts us close to the ecosystem that needs what we're building.
